Can't sell items for Gemcutter's Prism

In the currency tab or any other tab I can't list other currencies or items to sell / exchange for gemcutter's prism.

no option to select gemcutter's prism from the list of available currencies.

Any help please?

I was also going to bring this up...


I'm afraid I also don't have an answer, and lately the forum boys don't seem to be very helpful; just horribly critical and opinionated... overly pompous and disagreeable.

Let's hope someone can shed some light.

Let's hope someone replies with a legit answer. I have a feeling that they forgot to include it in the game menu's trade options for currencies.
